[vtkusers] Creating new vtkImageSources

[Dubois, John R (MED)]

Thanks.

I am reading in a VFF file - which creates a simple contiguous block of
single value (i.e. short int) pixels. However, the data does not appear
to be laid out correctly for the vtmImageImport object. The structure
appears to be the same as in this example.

I will try permuting the dimensions....
